If you wish to see an idealized version (without the influen= ce of the solar wind), you can use Celestia with the magnetic field add-= on. The basic program can be found at http://www.shatters.net/cele= stia and the addon at http://www.celestiamotherlode.com. There are= a couple of tweaks to the add-on that allow you to show (or not) variou= s field lines and particle pathways.
